+            <p>New Features</p>
+            <ul>
+                <li>Depth Masking: Create masks based on how far objects are from the camera. Useful for faking background blur, adding lights that blend naturally into the scene, or isolating subjects at a certain distance.</li>
+                <li>Quick Inpainting: A new local inpainting model that does a much better job at removing unwanted objects. Runs on device and does not require the RapidRAW-AI-Connector.</li>
+                <li>Library Performance: Rewrote large parts of the library loading code. Thumbnails are now only rendered when visible on screen, making large libraries feel much snappier. Also added a flat list view as a new thumbnail mode.</li>
+                <li>ROI Rendering Improvements: Smoother rendering while zoomed in, plus a new dropdown to pick your preferred quality level for live previews.</li>
+            </ul>
+            <p>Core Improvements</p>
+            <ul>
+                <li>Updated keyboard shortcuts for masking, especially for the brush tool.</li>
+                <li>Color gradient for the temperature and tint slider track.</li>
+                <li>Improved loading spinner to show actual progress when applying batch adjustments.</li>
+                <li>Various bug fixes under the hood.</li>
+            </ul>
